The emergence of weedy rice ( f. ) has been considered as a serious global agricultural problem in recent decades. To better understand its speciation, here we assembled the complete chloroplast genome of f. with the length of 134,502 bp. The assembly contains a large single-copy (LSC, 80,549 bp), a small single-copy (SSC, 12,347 bp) and a pair of inverted repeats (IRa and IRb, 20,803 bp each). A total of 132 unique genes were annotated, including 82 protein-coding genes, 42 tRNA genes and eight rRNA genes. Phylogenetic analysis showed that f. ( type) appears closely related to cultivated rice rather than wild rice, supporting the hypothesis that weedy rice originated from cultivated rice.
近几十年来,杂草稻(f.)的出现被视为一个严重的全球农业问题。为了更好地理解其物种形成,我们在此组装了长度为134,502 bp的f.的完整叶绿体基因组。该组装包含一个大单拷贝(LSC,80,549 bp)、一个小单拷贝(SSC,12,347 bp)和一对反向重复序列(IRa和IRb,各20,803 bp)。总共注释了132个独特基因,包括82个蛋白质编码基因、42个tRNA基因和8个rRNA基因。系统发育分析表明,f.(类型)似乎与栽培稻密切相关,而不是与野生稻密切相关,这支持了杂草稻起源于栽培稻的假说。
